Minnetonka, MN Noise Ordinances: Vehicle Noise (2026)

Minnetonka City Code § 850.010 prohibits three vehicle noises by name. Subdivision 1 bars the continual sounding of a horn, siren, or other signaling device on a motor vehicle for a period of at least 15 seconds, even though interrupted by short gaps in sound, except in cases of imminent danger or emergency. It also bars amplifying the sound a signaling device emits beyond that of its design.

Subdivision 7 covers the operation of a motor vehicle, a minibike or other similar vehicle or device in a way that results in the squealing of tires or the creation of other noise. The rule applies on a highway, private road, public or private parking lot, driveway, or other property in the city, and it requires that the noise unreasonably disturb a reasonable person of ordinary sensitivity. The exception is when there is reason to do so for the safe operation of the vehicle.

Subdivision 8 prohibits the use of a compression release engine braking system, commonly known as a jake brake, except in an emergency. Unlike the horn and tire rules, it carries no reasonableness test.

Vehicle stereos fall under subdivision 2: between 10:00 p.m. and 7:00 a.m., sound plainly audible at a distance of 50 feet from any motor vehicle in which the device is located is prima facie evidence of a violation. Separately, § 850.015 subdivision 3 bars driving a minibike, snowmobile, or similar recreational vehicle not licensed for travel on public streets at any time other than between 7:00 a.m. and 10:00 p.m.

Section 850.020 exempts the operation of motor vehicles on public streets and highways in compliance with state and local laws, along with sirens and warning devices used by public safety personnel in emergencies and operation of locomotives and railroad cars.
